The air electric heater is primarily used to heat the required air flow from an initial temperature to the desired air temperature, up to a high of 850°C. It has been widely applied in aerospace, meltblown non-woven, film, chemical industry, and many scientific research and production laboratories in colleges and universities. Air heaters must withstand the oxidizing action of high-temperature air, hence stainless steel materials must be selected. The heating element of the air heater is a stainless steel electric heating tube. Multiple baffle plates are set inside the heater to extend the air's residence time within the heater cavity, thereby enhancing heat exchange efficiency. Appropriately increasing the number of heating tubes and boosting the installed power of the air heater can shorten the startup and heating time of the production line. The air electric heater has a broad range of applications: it can heat any gas, producing dry hot air that is moisture-free, non-conductive, non-flammable, non-explosive, non-corrosive, and with fast heating of the heated space (可控).
